Abstract (en)
[origin: EP3845287A1] An on-off hydraulic valve (10) with filtering function provides a shutter (19), which regulates the passage of fluid between an inlet (15) and an outlet (17) of the valve, with a cavity (20) having a first (20A) and a second (20B) separate chamber, and includes a removable, particulate collection closed structure (47), communicating with the inside of the valve; the closed structure (47) is equipped with a magnet (46) to attract ferromagnetic particles and inside it there are obtained a first (45A) and a second (45B) chamber communicating through a filter (37) which retains the inert particles; in the valve opening position the fluid from the inlet (15) flows into the first chambers (20A, 45A), passes through the filter (37), flows into the second chambers (45B, 20B) and flows out of the outlet (17); in the closed position the communication between the inside of the closed structure (47) and the inlet (15) and the outlet (17) of the valve is interrupted. This valve is very effective in filtration, compact and easy to clean.
